Twin story is a perfect platform to create interactive stories. For my own story, the first principle that I can relate is Coherence Principle. I put the pictures, related to text, in each page. The pictures will coherence with text to help learner learn better. Another related principle is Learner control Principle. By giving reader control of the next and previous step buttons, reader can read text on their own pace.

Twin story gives learner control of their choice in the story. Therefore, I think it is perfect for educate minors. By choosing action on their own, they will learn the consequences of their actions.  Teaching them by stories are always easier to reason with them.
